Hi guys ! I am proud to announce that the new version of Picobat is out. There is quite a long while since I have posted a new version of Picobat. Quite a lot of changes have been made since last year.

New features

There is two main new features interpreter multi-threading and operators precedence


The biggest flaw (in terms of execution speed) of Picobat under windows was certainly the need to start new dos9 processes regularly. Indeed, commands like echo test | find "test" require a new process to be started (FOR had a somehow similar behaviour). In a batch, where this commands can be ran hundred times, it resulted in a significant speed penalty.

The version 218.1 solves this by just spawning separate threads inside a single Picobat interpreter, So that it gets faster than ever !


Picobat behaviour used to be a bit awkward as since the very first versions the redirection operators (>) owned precedence over all conditional operators (&, &&, | and ||).

This behaviour has now changed and lines like the following are perfectly valid :

echo test > file & dir > fd

Compatibility between dos9 and cmd.exe has greatly been improved.

Minor changes

There is also a few minor changes since the last release:

  • The file searching functions has been strongly optimized.

  • Great improvement in the manual, especially for the English translation.

  • New, easy-to-use build system.

  • Lots of minor bug-fixes.
